Germany charges 22-year-old man with joining IS in Syria

German prosecutors have filed terrorism charges against a 22-year-old man accused of joining the Islamic State group in Syria and appearing in propaganda videos.

Federal prosecutors said Thursday that the German national, identified only as Tarik S. because of German privacy rules, was charged with membership in a foreign terrorist organization, disturbing the peace of the dead and deprivation of liberty among other things.

He's alleged to have joined IS around January 2014, fighting and manning a checkpoint where he held a truck driver for a day because he was transporting large quantities of cigarettes. He's also accused of appearing in IS videos, in one of which he mocked a decapitated corpse.

The suspect returned to Germany in March because his wife was pregnant. He was arrested at Frankfurt airport.
